Abstract

Twenty kinds of herbs were studied for the relationship between sugar content and Cold–Hot nature. The Fehling method was used for determining the total sugar content, the sulfuric acid-anthraquinone colorimetric method for measuring the total polysaccharides content, and the alkaline copper sulfate method for testing the monosaccharide content. After that, the obtained data were analyzed by the Fisher method. The 10 kinds of Hot herbs showed significantly higher total sugar content and monosaccharide content than the 10 kinds of Cold herbs, with P<0.05; however, they showed no significant differences in the total polysaccharides content, with P>0.05. A discriminant function was established by the Fisher method, with the group back substitution result of the Fisher analysis reaching 85%. The results demonstrate that there exists a certain relationship between the sugar content and the Cold–Hot nature of the 20 kinds of herbs. The Fisher analysis can be used to distinguish the Cold–Hot nature, and sugar is one of the material bases of Cold–Hot nature.

用Fisher分析法研究20种草本植物糖含量与冷热性的关系

研究了20种中草药的糖含量与冷热性质的关系。用Fehling法测定总糖含量，用硫酸-蒽醌比色法测定总多糖含量，用碱性硫酸铜法测定单糖含量。然后，用Fisher方法对得到的数据进行分析。10种热性药材的总糖含量和单糖含量显著高于10种寒性药材，p < 0.05;总多糖含量差异不显著(p < 0.05)。利用Fisher方法建立了判别函数，Fisher分析的群反代结果达到85%。结果表明，20种药材的冷热性与糖含量存在一定的关系。费雪分析可以用来区分冷热性质，而糖是冷热性质的物质基础之一。
